Engle Matrix Games
Matrix Game Rules: Start with a problem. Say what happens next. There is no order of play. Anyone can add to or alter what happens. All players may ask a player to roll if they don't like what they said. Roll 2d6. 7+ The action happens and cannot be altered. 6- It does not happen and cannot happen in the game. The game ends when the problem is solved.
That is the short form of Matrix Game rules. But of course it isn't that simple. There are MANY ways to play Matrix Games. One common form is for players to make arguments for what happens next. They say an action, a result from the action, and three reasons why it happens. A referee decides what they need to roll to succeed and other players may make counter-arguments for what they think happens instead. Players then roll to see which happens. There are many ways to do this but the oldest version of the rules used a sudden death roll off. Each player rolls for their own argument. If they pass their roll, they stay in the competition. If they fail, they drop out of the contest. The last argument standing happens. Events unfold and the players find out what happens.
For games to work, Matrix Games need a scenario. This is the "Matrix" of Matrix Games. A scenario lays out a matrix of information about the game world which key the players in on what they are to do. It may include maps, lists of characters, a central problem to be solved, lists of ideas and much more. The scenario doesn't say everything that can happen but gives a flavor of what might happen. The player's minds fill in the blanks to form a complete picture.
